Description

Technical Field

[0001] The invention relates to the field of parking machinery, and in particular to a double-tray type three-dimensional parking garage and a control method thereof. Background Art

[0002] Mechanical stereo parking garage is a kind of mechanical equipment that integrates vehicle handling, parking and storage. Warehouse-type mechanical stereo parking garage uses automatic navigation vehicles (hereinafter referred to as AGV vehicles) and vertical lifts to handle, park and store vehicles. Each parking space has a vehicle pallet that can be transported. The parking garage can be equipped with several vertical lifts, and each floor can be equipped with several AGV vehicles.

[0003] Usually, during the parking process, the vehicle is first parked on the vehicle pallet of the parking space, and then the AGV trolley on this floor takes the vehicle and the vehicle pallet from the parking space together and transfers them to the vertical elevator; the AGV trolley on this floor lifts and lowers to the target parking layer, and then the AGV trolley on this parking layer takes the vehicle and the vehicle pallet out together and transfers them to the parking space on this layer. Finally, the AGV trolley takes the vehicle pallet on an empty parking space on this layer and descends to the first floor through the vertical elevator, and then the AGV trolley on the first floor takes the vehicle pallet from the vertical elevator and places it on the parking space on the first floor. After the AGV trolley on the first floor sends the vehicle and the vehicle pallet into the elevator, it must wait in place until the elevator rises to park the vehicle and takes another vehicle pallet to descend before it can proceed to the next step, which cannot effectively utilize this window time; at the same time, during the time when the AGV trolley on the target parking layer is parking the vehicle and putting the empty vehicle pallet into the elevator, the elevator must wait on this floor, thereby making the parking efficiency low.

DETAILED DESCRIPTION

[0046] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

Words such as "connect" or "connected" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship also changes accordingly.

[0048] Firstly, the double-tray type three-dimensional parking garage with a buffer area according to an embodiment of the present invention is described in detail below with reference to the accompanying drawings.

[0049] Figure 1 This is a schematic diagram of the elevation layout of a double-tray multi-story parking garage with a cache area according to an embodiment of the present invention. The multi-story parking garage includes: multiple parking floors, and at least one vertical elevator 100 running through the entrances and exits of each parking floor, and each parking floor includes at least one automatic navigation vehicle 200.

[0050] Specifically, if Figure 1 and Figure 2 As shown, the vertical lift 100 includes: a lifting platform 110, a first conveyor 120 and a second conveyor 130. The lifting platform 110 is provided with a platform access channel on one side close to the entrance and exit of the parking layer, and the automatic navigation vehicle 200 is provided with a lifting mechanism for lifting / lowering the vehicle pallet 300 under the vehicle pallet 300, so that the automatic navigation vehicle 200 can park the vehicle pallet 300 into the lifting platform 110 through the platform access channel. The first conveyor 120 is arranged on the lifting platform 110 and is arranged corresponding to the access channel. The first conveyor 120 can transport the vehicle pallet 300 carrying the vehicle 600 into the access channel by rotation; the second conveyor 130 is fixed under the lifting platform 110 and keeps a certain distance from the bottom of the lifting platform 110. Thus, an upper and lower layer structure can be formed with the first conveyor 120 for parking the vehicle pallet 300. In addition, as Figure 3As shown, the parking layer includes a plurality of parking spaces 400 provided with vehicle pallets 300, and a buffer zone matching the lifting platform 110 is provided at the platform access channel of the vertical lift 100, and a third conveyor 500 is provided in the buffer zone. When the vertical lift 100 is lifted to the target parking layer, the third conveyor 500 can be aligned with the first conveyor 120 and the second conveyor 130. Thus, the third conveyor can transport the vehicle pallets 300 carrying vehicles 600 and the empty vehicle pallets 300 into the vertical lift 100. It should be noted that Figure 1 Schematic diagram of the elevation layout of a double-tray three-dimensional parking garage according to an embodiment of the present invention. In actual application, the number of vertical lifts 100 can be increased according to the needs of the parking garage.

[0051] like Figure 1 and Figure 3 As shown, in one embodiment of the present invention, a vehicle loading tray rack 410 is provided on the parking space 400 of the parking layer, and the vehicle loading tray rack 410 is used to carry the vehicle loading tray 300. Thus, the automatic navigation vehicle 200 can complete the parking procedure by transporting the vehicle loading tray 300 to the vehicle loading tray rack 410.

[0052] like Figure 2 As shown, in one embodiment of the present invention, the lifting platform 110 includes: two groups of structural members 140, the two groups of structural members 140 are symmetrically fixed at the bottom of the lifting platform 110, and the second conveyor 130 is connected between the two groups of structural members 140. Therefore, the height of the structural members 140 can be customized according to the needs, so as to adjust the distance between the second conveyor 130 and the bottom of the lifting platform 110, reduce the overall height of the vertical lift 100, and complete the vehicle storage and retrieval process faster.

[0053] like Figure 3 As shown, in one embodiment of the present invention, the parking layer is provided with at least one lane 700 to separate a plurality of parking spaces 400. Thus, by dividing the parking spaces 400 by the lanes 700, the automatic navigation vehicle 200 can also move along the lanes 700 while playing a planning role, effectively improving the maneuverability of the automatic navigation vehicle 200.

[0054] like Figure 2 As shown, in one embodiment of the present invention, a fixing frame 111 is provided above the lifting platform 110, and the fixing frame 111 and the lifting platform 110 form a car structure. Thus, the fixing frame 111 and the lifting platform 110 form a stable car structure, which can effectively improve the structural strength of the vertical lift 100.

[0055] In one embodiment of the present invention, the double-tray stereoscopic parking garage further comprises: a controller (not shown), which is electrically connected to the vertical lift 100, the first conveyor 120, the second conveyor 130, the third conveyor 500 and the automatic navigation vehicle 200. Thus, the controller can dispatch the vertical lift 100 and the automatic navigation vehicle 200 according to the real-time number of vehicles 600 in the stereoscopic parking garage, and control the start and stop of the first conveyor 120, the second conveyor 130 and the third conveyor 500, thereby effectively improving the efficiency of storing and retrieving vehicles in the double-tray stereoscopic parking garage.

[0056] The present invention also provides a control method for a double-tray multi-story parking garage with a cache area, which is applied to the multi-story parking garage described in the above embodiment. The specific structure of the multi-story parking garage has been described in detail in the above embodiment, and specific reference may be made to the double-tray multi-story parking garage with a cache area in the above embodiment.

[0057] The control method of the double-tray stereoscopic parking garage will be described in detail below with reference to the accompanying drawings.

[0058] Figure 4 A flowchart of a double-tray type three-dimensional parking garage control method according to an embodiment of the present invention is specifically described. The flowchart includes S410-S440, and several steps are described in detail below:

[0059] S410: When a vehicle parked in a parking space on the first floor of the three-dimensional parking garage needs to be stored in a target parking floor, the controller controls the vertical lift to descend to the first floor.

[0060] Specifically, at least one parking space is provided at the entrance and exit of the first floor of the three-dimensional parking garage, and a vehicle loading tray is provided on the parking space. When a vehicle needs to be parked in the parking garage, the vehicle can be parked in the parking space. At this time, the controller can control the lifting platform to descend to the first floor, so that the automatic navigation vehicle on the first floor can move the vehicle loading tray carrying the vehicle from the parking space on the first floor into the vertical lift.

[0061] S420, the automatic navigation vehicle on the first floor transfers the vehicle-carrying pallet carrying the vehicle to the first conveyor, and takes out the vehicle-carrying pallet pre-stored on the second conveyor.

[0062] Specifically, the automatic guided vehicle on the first floor transfers the vehicle pallets loaded with vehicles to the third conveyor in the buffer zone on the first floor; the third conveyor is started, and the vehicle pallets with parked vehicles are transferred to the first conveyor through the platform access channel; the vertical lift rises to align the second conveyor with the third conveyor, and the second conveyor is started to transfer the pre-stored vehicle pallets to the third conveyor, so that the automatic guided vehicle can transport the vehicle pallets to the parking spaces. As a result, the vertical lift only needs to stop on the first floor once, and it can transport the empty vehicle pallets needed on the first floor to the first floor while loading the vehicle pallets loaded with vehicles, effectively improving the efficiency of picking up and retrieving vehicles in the three-dimensional parking garage.

[0063] S430, the vertical lift is lifted to the target parking floor, the vehicle pallet pre-stored on the third conveyor of the target parking floor is transferred to the second conveyor, and the first conveyor is started to transfer the vehicle pallet with the parked vehicle to the third conveyor.

[0064] Specifically, the vertical lift is lifted to the target parking floor and aligns the second conveyor with the third conveyor in the buffer area of ​​the target parking floor. The third conveyor is started to transfer the pre-stored vehicle pallet to the second conveyor. The vertical lift is lowered to align the first conveyor with the third conveyor of the target parking floor, and the first conveyor is started to transfer the vehicle pallet carrying the vehicle to the third conveyor.

[0065] S440, the automatic navigation vehicle at the target parking floor transfers the vehicle pallet with the parked vehicle from the third conveyor to the parking space at the target parking floor, and takes out the vehicle pallet from the nearby unparked parking space and transfers it to the third conveyor at the target parking floor.

[0066] It should be noted that the above flowchart describes the process of parking a vehicle once. When a new vehicle is parked on the first floor of the three-dimensional parking garage, the method of S410-S440 in the above flow is repeated. In addition, the above is the process when a vehicle is parked in the three-dimensional parking garage. When it is necessary to take out a vehicle, the steps in the above flow can be performed in reverse order, and no further description is given here.

[0067] Therefore, according to the double-tray type three-dimensional parking garage with a buffer area and the control method of the embodiment of the present invention, by setting up two layers of conveyors in the vertical lift to store the loaded vehicle trays and the empty vehicle trays respectively, the efficiency of storing and retrieving vehicles in the three-dimensional parking garage can be effectively improved. At the same time, the automatic navigation vehicle can put the trays on the conveyor and the conveyor can move them automatically, further improving the efficiency of storing and retrieving vehicles in the three-dimensional parking garage.

[0068] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
